We had a wonderful stay at Poseidon Hotel. The location is great, just a short walk from the port and close to everything we needed. The room was clean, comfortable, and well taken care of. Marina was incredibly kind and welcoming, always ready to help us with anything we needed. We would definitely recommend Poseidon Hotel !

Marina and Spiros were lovely, they made our stay extremely enjoyable going above and beyond to accommodate us. The rooms were also very clean, comfortable and the pool area was really nice too with a great bar. The port is a peaceful place with the hotel a stones throw away, the bus into town was just down the hill and no stress to get to. Definitely a place worth staying.

⸻ I stayed at Hotel Poseidon in Ios recently, and honestly, it blew me away. From the second I arrived, Marina and the team were so friendly — they made me feel like I was staying with family. They were always happy to help, whether it was giving tips on the best beaches, helping with transport, or just saying hi with a big smile every morning. The location is perfect — super close to the port and with amazing views over the harbour. My room was bright, clean, and comfy, and I loved having a balcony to chill on with my morning coffee. The pool was definitely one of my favourite parts — it’s peaceful, spotless, and there are loads of loungers, which is ideal for relaxing after exploring the island. What really stood out for me was how welcoming everyone was and how good the value is. It’s such a comfortable, easy place to stay, and it made my trip to Ios so much better. If you’re looking for somewhere that’s friendly, well-located, and has everything you need, I can’t recommend Hotel Poseidon enough. I’ll 100% be back!

Nothing - everything was perfect.

If I could give Hotel Poseidon more than 5 stars, I absolutely would. We stayed here for part of our honeymoon, and from the moment we arrived, it was clear this wasn’t just a hotel – it was like the owners were extending their home for you. This is a truly family-run hotel in every sense of the word, and the warmth, kindness, and care from the owners is unlike anything I’ve experienced in all my years of travelling. They genuinely couldn’t do enough for us. We had booked our stay very last minute and arrived far earlier than check-in because of our ferry, yet they immediately went above and beyond to prepare our room early. Not only that, but they surprised us with beautiful flowers and homemade biscuits to celebrate our honeymoon – such thoughtful, personal touches that meant the world to us. The hotel itself is spotless – our room was bright, airy, and perfectly clean, with everything we needed. The location couldn’t be more convenient: right next to the port, surrounded by great restaurants, and only moments from the bus stop, making it so easy to get to Chora or explore the rest of the island. Halfway through our stay, I fell unwell, and their kindness reached a whole new level. They checked in on me, made sure I was comfortable, and did everything they could to help me feel better – small gestures that spoke volumes about the sort of people they are. Then, when bad weather meant our ferry off the island was cancelled, they instantly reassured us and let us stay another night, removing all the stress from what could have been a difficult situation. In a world where so many hotels feel impersonal, Hotel Poseidon is the most wonderful reminder of what hospitality should be – genuine, heartfelt, and full of care. We left feeling like we’d stayed with friends, and I cannot recommend this place highly enough. If you’re visiting Ios, do yourself a favour and book here.

My stay at Hotel Poseidon was absolutely perfect, and I couldn't be more delighted with my experience! As soon as I arrived, I was warmly greeted by the lovely staff, who were always smiling and attentive. My heart goes out to Marina, who made my stay even more special with her kindness and professionalism. She's just incredible! The hotel's impeccable cleanliness is extremely appreciated. The rooms are spotless and comfortable. The location is ideal, making it easy to enjoy the surrounding area, while at the same time offering a peaceful atmosphere. Every morning, waking up to such a beautiful landscape is pure bliss. The pool is also a real asset: spacious, clean and a great place to cool off or relax in the sun. Everything was absolutely perfect, from the service to the ambiance to the facilities. Hotel Poseidon is an address I can wholeheartedly recommend for an unforgettable vacation in Greece. I can't wait to go back!

Not wheelchair/disabilty friendly. If you want to go into the main part where all shops are it’s about a 30ish minute walk or you’ll have to get a bike. Shower was small

The owner of this property is amazing!!! She meets all your needs and you’ll constantly see her around where she will check up on you. She even went out of her way to drop us backed cakes and biscuits. This port is a great location if you’re getting the ferry.

The Posiden Hotel was a perfect place to stay. It is right next to the ferry port. The bus into the chora is very close as well. The staff are extremely friendly and helpful. Great recommendations for hotels and things to do while we were there. The swim up bar was a great treat on a very hot day. We were lucky enough to receive homemade cakes and biscuits.

We have to be very honest this hotel is a must in Ios. If you have a chance to go to this island one day don’t hesitate to book a room there. They have everything from a fully fonctionnal room to a fantastic pool/bar. The owners are good and honest people willing to treat their guests as family that’s what hôtellerie is all about ! Thank you

The steps were about the only negative but to be fair the property does state that on the site. It does have a disabled stair lift and staff helped with carrying bags around the hotel including from the bottom steps. The bathroom was small and maybe converting it to a full wet room might be a better solution.

Hotel is located at the Port visible from when you leave the Ferry so no need for transport. On arrival our host Marianna was very friendly and welcoming, it is a family run hotel where the staff could do no more for you. When we arrived a couple were arriving at the same time and they come back to this place every year for a week. The Pool was glorious and the poolside bar with bar stools in the pool were a lovely touch. We didn't use the games room which is beside the pool and there are plenty of restaurants and bars around the port catering for many different cuisines. The local bus service every twenty minutes went to the the main town of Ios and another beach the far side of the island. (€2 a trip)
